At first first embodiment and the correction thereof of air heat source type air conditioner such among the present invention for example are illustrated with reference to Fig. 1-Fig. 4.
Indication equipment has the basic structure of air heat source type air conditioner of the pattern of an air supply opening SA among Fig. 1.As shown, each constitution equipment of the heat pump circuit of formation air heat source type air conditioner is housed in the outer container C that is equipped with the regulation shape of selecting in the place.And outer container C is provided with the outside air input port OA of input outside air, carries out the air supply opening SA of air feed by the exhaust outlet EA of the return-air mouth RA of indoor input return-air, exhaust from the room outside with to the air-conditioning object space, confession, the exhaust of the air that the confession by the pipeline stipulated etc., exhaust equipment can be stipulated by the aftermentioned air flue that forms in outer container C.
Being formed with the first thermal medium peripheral passage that constitutes heat pump circuit in outer container C (is the heat pump circuit that adopts the thermal medium of the gas-liquid variation that utilizes fluorine series cold-producing medium and ammonia etc., be called " refrigerant loop " below), for the second thermal medium peripheral passage that forms Air Conditioning (for do the loop of thermal medium with water or non freezing solution, be called " brine loop " below) and the first heat exchanger EX1 of gas-liquid contact-type described later is supplied with the spray water peripheral passage (make the loop of its cooling as condenser as the time spent at the first heat exchanger EX1, be referred to as " chilled(cooling) water return (CWR) " below) of spray water.
At first, the first thermal medium peripheral passage (refrigerant loop) that constitutes heat pump circuit is described, this first thermal medium peripheral passage relies on the gas-liquid first heat exchanger EX1, compressor COM, cross valve QV, the second heat exchanger EX2 that carries out heat exchange between first thermal medium and second thermal medium, the first expansion valve EV1, the second expansion valve EV2 and the liquid/gas separator AC that configuring pipes connects and evacuating air carries out heat exchange, constitutes by conversion cross valve QV to make the heat pump circuit of the cold-producing medium of regulation with the prescribed direction circulation.The current return circuit that is plugged with check-valves V1, V2 is set on the mechanical first expansion valve EV1 and the second expansion valve EV2, thus the expansion valve that may pass through according to the loop direction selection cold-producing medium of cold-producing medium.Adopt such structure, the first thermal medium peripheral passage relies on the conversion of cross valve QV when making heating operation, make the sequential loop of cold-producing medium, thereby can supply with warm brine loop described later by compressor COM → time logical valve → second heat exchanger (condenser) EX2 → check-valves, 1 → the second expansion valve EV2 → first heat exchanger (evaporimeter) EX1 → time logical valve QV → liquid/gas separator AC-compressor COM.In contrast, when making refrigerating operaton, rely on the conversion of cross valve QV, make the sequential loop of cold-producing medium, thereby can supply with low temperature brine loop described later by compressor COM → cross valve QV → first heat exchanger (condenser) EX1 → check-valves, 2 → the first expansion valve EV1 → second heat exchanger (evaporimeter) EX2 → time logical valve QV → liquid/gas separator AC → compressor COM.
The following describes the second thermal medium peripheral passage (brine loop), the second thermal medium peripheral passage by and first thermal medium (cold-producing medium) between carry out the second heat exchanger EX2 of heat exchange, between air and second thermal medium (salt solution), carry out the 3rd heat exchanger EX3 of heat exchange and pump P1 constitutes.Thereby according to the method for operation of above-mentioned heat pump circuit, obtain warm or low temperature, heat or cool off by the 3rd heat exchanger EX3, and can reach only temperature adjusting by the second heat exchanger EX2.
Structure to spray water peripheral passage (cooling water path) and the gas-liquid contact-type first heat exchanger EX1 is illustrated below.Spray water peripheral passage equipment has: do not add among spray line SP, the bosh (bottom tank) WB, the pump P2 that deposit spray water, the configuring pipes that makes cooling water circulation, the figure expression be contained in filter in the configuration pipeline, for the TVS that disperses that falls few spray water be the feed pipe of the water yield of replenishing the spray water of dispersing and evaporating.The first heat exchanger EX1 is for example vaporation-type condenser, relies on sprinkler pipe SP that the sprinkling of the first heat exchanger EX1 is taken away evaporation latent heat by heat exchanger, takes away the steam that is produced by evacuating air simultaneously, realizes highdensity passage of heat.Upwards drawn again by cooling water circulating pump P2 and spray to the first heat exchanger EX1 bearing the back by bosh WB by the cooling water that sprayed by sprinkler pipe SP.Certainly, even also can carry out just need not the operation of spray water peripheral passage under the situation of sufficient heat exchange not spraying cooling water.
Below formed air flow path in the outer container C is illustrated.In this form of implementation, in such air conditioner, mainly be formed with three circulation of air AF1, AF2 and AF3 in the outer container C.The first air flow path AF1 is for linking the air flow path of return-air mouth RA and air supply opening SA, inserts promisingly to remove the filter F 2 of dust in the air and for regulating the adjuster RD of air capacity midway.The second air flow path AF2 is for connecting the air flow path of outer air input port OA and first air flow path, promising filter F 1 of removing dust in the air is set midway and is the adjuster OD of adjusting air capacity.And the 3rd air flow path AF3 is the air flow path of the connection exhaust outlet EA and the first air flow path AF1, but the 3rd air flow path AF3 more is being communicated with the first air flow path AF1 near the position of return-air mouth RA than second air flow path that imports outside air.Thereby be respectively arranged with scavenger fan EF and air-feeding ventilator SF near the exhaust outlet EA and near the air supply opening SA.
Below simple declaration is done in the operation of the air conditioner of above-mentioned such formation.At first, be taken into and supplied with the air of air-conditioning object space by air supply opening SA by outside air inlet OA, RA is taken in the outer container C by the return-air mouth.And according to this air conditioner, by driving scavenger fan, the part of return-air is sent to the gas-liquid contact-type by the 3rd air flow path AF3 the first heat exchanger EX1 carries out heat exchange at this and first thermal medium (cold-producing medium).And drive the first thermal medium peripheral passage (refrigerant loop) by mode (heating system or refrigeration modes) with regulation, provide warm or low temperature to the second thermal medium peripheral passage (brine loop), the 3rd heat exchanger EX3 will flow through outside air and/or the return-air heating of the first air flow path AF1 or be cooled to temperature desired and offer the air-conditioning object space again.Like this, in fact the heat pump mechanism of this air conditioner imports with the evacuating air within the air capacity of outside and is used as thermal source, and does not think that the above air of export-oriented air capacity of keeping the IAQ in the space chamber and being taken into uses as thermal source.Thereby may constitute and need not the apparent air heat source type air conditioner of going up the complete independent decentralized of thermal source.And since thermal source with idle call in constitute the thermal medium peripheral passage respectively, thereby alleviated restriction in for example second heat exchanger EX2 configuration or the like, and the aggrandizement apparatus structural free degree.And because first, second thermal medium EGR carries out the rotating speed control of pump independently of one another, thereby can use the best methods of operation such as choice reaction performance in the multiple method of operation of known control method cause, saving energy consumption.
First modification that shows air conditioner shown in Fig. 1 among Fig. 2.Though the basic structure of air conditioner shown in Fig. 2 is identical in fact with air conditioner shown in Figure 1, but air conditioner shown in Figure 2 has heat storage tank HB, disposes the coiled pipe EX4 with the 3rd heat exchanger EX3 of second thermal medium peripheral passage heat exchange connected in series in this heat storage tank HB.This heat storage tank coiled pipe for example when icing accumulation of heat, can freeze by the coiled pipe outer periphery, also adopt with flow through fluid in the coiled pipe do indirect heat exchange in melt formula ice this just easily.Trough inner water is only done free convection, and the structure of groove is just very simple.And adopt connected in seriesly, and the configuration that discloses the heat exchanger of flat 7-198161 with Japan Patent is compared, and structure is simpler.In the second thermal medium peripheral passage, be inserted with valve V3-V6, these valves V3-V6 is done appropriate switching just can constitute desirable peripheral passage.That is when utilizing that night, cheap electric power carried out accumulation of heat in the heat storage tank HB, valve V3, V6 close, valve V4, V5 open, and the heat exchange coiled pipe EX4 and the second heat exchanger EX2 is connected in series.In contrast, in reclaiming heat storage tank HB, stored up hot the time, valve V4, V6 close, valve V3, V5 open, and make second thermal medium in turn along heat exchange coiled pipe EX4 → second heat exchanger EX2 → the 3rd heat exchanger EX3 circulation.So just constitute as shown in Figure 2, and can reclaim the heat of being stored up among (taking-up) heat storage tank HB.And can start compressor COM and in the second heat exchanger EX2, the heat of being accumulated among the heat storage tank HB be reclaimed in cooling of second thermal medium or heating simultaneously, at this moment the delayed heat that is generated in the heat pump circuit might be stored up into heat storage tank, even thereby the volume controlled of not carrying out compressor COM also can turn round.And when in heat storage tank HB, not having storage or saving hot, perhaps need not take out when hot, valve V4, V5 are closed, valve V3, V6 open, and the heat-exchanger coil EX4 of heat storage tank HB is made a circulation, thereby can carry out the running same with structure shown in Fig. 1.And in the horse stable example, though be heat storage tank HB to be set in the inside of outer container C, but heat storage tank HB and heat exchange coiled pipe EX4 also not necessarily must do whole the setting with other heat exchangers group, for example take to be provided with heat storage tank HB adjacent with air conditioner shown in Figure 1 and are connected such structure with appropriate pipeline and also can.And as in machine equipment first and second thermal medium peripheral passages only, and be set to utilize the duct arrangement delivery outlet (water swivel) of accumulation of heat water to constitute main frame like this, then just increased the free degree that the position is set of heat storage tank HB, perhaps also might when enlarging the refrigeration construction, utilize the tank that has been provided with for existing structure.
The part change example that shows air conditioner shown in Fig. 2 among Fig. 3.Air conditioner shown in Figure 3 is with the different of air conditioner shown in Figure 2, the loop direction of the salt solution that circulates in the second thermal medium peripheral passage (brine loop).Certainly, as shown in Figure 2, even make the salt solution order by pump P1 → second heat exchanger EX2 → the 3rd heat exchanger EX3 → heat exchange coiled pipe EX4 → pump P1 circulation, also can reach superior effect of the present invention, but as if shown in Fig. 3, make and make the structure of salt solution order, then can carry out the higher running of power by pump P1 → heat exchange coiled pipe EX4 → the 3rd heat exchanger EX3 → second heat exchanger EX2 → pump P1 circulation.That is as the formation adopting, the evaporating temperature of first thermal medium or adiabatic condensation temperature become second heat medium temperature near the 3rd heat exchanger EX3 outlet, i.e. return-air air themperature, thus can improve the effect coefficient in the first thermal medium loop.And the pump P1 that can between the 3rd heat exchanger EX3 and the second heat exchanger EX2, be provided with.Take such structure, the heat that pump took place in making refrigerating operaton is absorbed, and second thermal medium that becomes high temperature is provided for second heat exchanger, thereby can move expeditiously.
Be illustrated in the modification that is added with several heater H1-H3 on the structure of air conditioner shown in Figure 2 in addition among Fig. 4.That is in this conversion example, the heater H 1 of the groove water among the promising heating heat storage tank HB is set, the heater H 2 of promising heating salt solution is set in the second thermal medium peripheral passage and in the 3rd air flow path AF3, is set to heat the heater H 3 of the evacuating air that thermal source uses.Take such structure, for example wait in the winter time and can not guarantee under enough warm situations,, just can improve the operational efficiency of air conditioner by the medium heating of each heater H 1-H3 to regulation.When particularly making heating operation in the winter time, heater H 3 just can be replenished, because first heat exchanger is used as evaporimeter, stop the sprinkling (gas-liquid contact function) of spray water, can not surpass the heat of vaporization that makes cold-producing medium by being carried out the thermoregulator indoor exhaust that obtains with outside air with by situation.
Below several methods of operation of the air conditioner that has heat storage tank such among Fig. 2-Fig. 4 are done simple declaration.
